Problem of Hydroelectric Resources Management: Numerical Approach

In this work we analyze an optimal control problem for a system of two hydroelectric power stations in cascade with reversible turbines. The objective is to optimize the profit of power production while respecting the system’s restrictions. Some of these restrictions translate into state constraints and the cost function is nonconvex. This increases the complexity of the optimal control problem. The problem is solved numerically and two different approaches are adopted. These approaches focus on global optimization techniques (Chen-Burer algorithm) and on a projection estimation refinement method (PERmethod). PERmethod is used as a technique to reduce the dimension of the problem. Results and execution time of the two procedures are compared.

Shopper Centric Category Management in Convenience Stores: a Qualitative Study

The literature shows that category management is an important concept and tool for retailers and suppliers, but that there is a trend to move to a more shopper-centric category management approach, linked to the shoppermarketing approach. However, the knowledge on this issue is scarce on some retailing sectors, like convenience stores. The present study is focused on convenience stores, with the main purpose of finding out to what extent non-major food retailers successfully adopt a shopper-centric category management. The study is relevant in order to evaluate if a more shopper-centric approach is adequate to smaller companies/stores. To accomplish that goal, an exploratory qualitative study was conducted among convenience store retailers and suppliers. Six semistructured face-to-face interviews were conducted with Commercial Directors and Trade Marketing Managers. This data was complemented with thirteen interviews with shopper marketing experts. The data was analyzed using thematic content analysis technique, identifying themes, categories, subcategories, units of meaning and relations. The results revealed that convenience store retailers use some of the principles and techniques of the shopper-marketing and shopper-centric category management approaches, which they do in a non-standardized and non-formal approach or process. Their suppliers (the manufacturers) do it in a more formal and structured manner, probably as a result of previous interaction with major supermarkets chains. Both direct and indirect evidences of a shopper-centric approach were found, which, however, were slight, discrete and not formal.

Quality Management

The purpose of this chapter is to enable registered health and social care prac - titioners to assume a clinical and/or a professional leadership role in quality management in the health and social care sectors. The contents in this chap - ter will strengthen the management competences of practitioners working in these sectors, including critical thinking, critical reflection, problem solving and decision -making, thus improving the quality in health and social care services.

Intercultural Management

Globalization has increasingly brought permanent contact with people whose cultural background is different from what many would consider their ‘own’ culture. The area of intercultural management is of critical interest due to the impact of increased European and global migration, which has required health and social care leaders and managers to develop competency to respond to the diversity and changing needs of their workforce and service users. The communities within the European Union are now often characterised by significant diversity whether at cultural, social, or psychological levels. The purpose of this chapter is to enable health and social care practitioners to assume a clinical/ professional leadership role in quality intercultural management in the health and social care sector. This chapter will focus on developing health and social care practitioners’ knowledge and understanding in the area of intercultural management within contemporary health and social care organisations. It will focus on the critical application of knowledge to practice through the provision of underpinning knowledge, understanding and debates surrounding contemporary issues and practices in the areas of intercultural management. Many practitioners accessing this information may already work in the heath/social sector and this critical focus on intercultural and diversity management has the potential to improve the quality in health and social care services through the critical application to practice.
